Unreal Engine 4.7: Assertion failed: Det != 0.0f

Hello,

I try to port an existing game to 4.7 and get a crash in the editor as soon as I open a user interface. I think it might have to do something with zooming in or out. The error is:

2015.01.26-07.54.40:648][511]LogContentBrowser:Verbose: The content browser source was changed by the sources view to '/Game/MMO/Blueprints/UserInterface'

Does somebody have an idea what this could be? Opening the very same interface under 4.6.1 works.
